Abstract: An electrical generator is powered by the kinetic energy in ocean waves breaking at the shore. Waves are directed up an inclined surface through which an intake port is defined at a level substantially below the average wave height and extending across the entire length of the generator. Water entering the port is directed to drive the blades of a turbine located below the inclined surface but above the normal water level. Water overshooting the port is collected as it flows back down the surface by a second port which similarly feeds the water to drive the turbine. Water overshooting the top of the inclined surface is collected in a flow-reversing channel and likewise directed to drive the turbine. The system is mounted on wheels which are movable on rails extending from the ocean floor onto the beach, whereby the system can be moved to optimum position for different tidal conditions.
